The following procedures are required to install the remote charge pressure filter
manifold.
Remove the reducer fitting, located at charge pressure gauge port, from pump end
cap. (This part will not be used with the remote charge pressure filter option).
Install the filter manifold into the port on the side of the housing. The hydraulic tube
should enter its mating bore in the pump end cap with a low force.
NOTE: Failure to install the filter manifold to a sufficient depth in the end cap will
result in insufficient engagement of the tube in the end cap bore. This may allow
unfiltered oil to bypass the filter and enter the charge system.
After the filter manifold is installed to the proper depth, rotate the manifold to the
desired position.
While holding the filter manifold in the desired position, use a 1-3/8" open end wrench
to tighten the swivel lock nut to 52 Ft. Lbs. (for 042 frame size pumps) or a 1-5/8"
open end wrench to tighten the swivel lock nut to 90 Ft. Lbs. (on 055 thru 130 frame
size pumps).

In preparation for installing the control, place a new gasket on the
housing. Inspect to assure that the control orifice check valve and
spring are in their proper position in the control.
Engage the pin on the control linkage in the mating hole in the link
attached to the swashplate.
Set control into place and move control lever both directions to check
proper engagement of control linkage pin. Proper engagement will be
indicated by centering torque as the lever is moved from center. Non-
engagement of control linkage pin is indicated by lack of centering
torque as the lever is moved. In case of non-engagement remove the
control and repeat the above procedure.
Move the control into place against the pump housing, align the gasket,
and install the screws.
NOTE: For 042 pumps, the rear/center control mounting screw installs
into a "thru" hole, and has a sealing washer installed under its head.
Torque the screws to 12 Ft. Lbs.
